Abstract
We present here an efficient method for selecting high luminosity and massive high redshift clusters of galaxies, crucially important tools in cosmology. By selecting bright and extremely X-ray loud (high F(X)/F(V)) sources, we were able to identify 2 high redshift (z=0.45 and z=0.89) clusters so far and we have evidence for at least one more candidate at 0.4<z<1.1 out of a total of 16 selected sources.
